IMPROVEMENT IN HARROWS.

Th Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern;

`Be it known that'I, ISAAC 0mm, of West Chester,

in Butler county, in the State of Ohio, have invented certain new and useful Improvements in Harrows; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 represents a top or plan view of my imy proved harrow, when opened for use.

Figure 2 `represent-s the same, when folded together for transportation from place to place, it being atransverse sectional view.

My invention consists in certain improvements on the harrow for which I obtained Letters Patent dated March 24, 1868, my object being to cheapen and sirnplify the construction of the sectional hinged barrow, `which may be transported upon fixed runners attached to the upper side of the structure,- as hereinafter fully described.

In the accompanying drawings- A B O denote the three sections of the hal-row, the

rails a. of which are secured with bolts to the iron bars' b, to which the hinges are connected.

D D denote the runners, which rare formed of bent bars of iron, which are bolted at each end to the rails of the harrow a. l The hinges are so formed and arranged as to permit the vsections A and C to "be folded inward after the harrow is turned over to rest upon its runners D.

Harrows of various constructions may be provided ,with theskeleton runners D, upon which the harrow The two outer rails ofthe side sections may be made wider and heavier than the others, which will cause the wings A and O to hug the ground more closely when the harrcw is iu use.

When the barrow is so made that the two wings or sections A O will, when folded, come in contact, the points 'of the teeth will all Abe enclosed within the three sections of the barrow, and consequently there will'be no danger of accidents resulting from carelessness, which might occur by the attendant falling upon the exposed teeth.

The runners D are of iron, and secured by bolts to the two outer rails a.' of the central section B of the barrow.

The hinges are formed by loops in the ends of the bars b, through which the rods R are inserted.

The teeth g are inserted through the rails a a a', and when the barrow is folded, as represented in fig. 2, the points 'of ,the teeth will be enclosed within the three sections A -B C, and the harro'w may be' drawn upon the ground upon its runners D D, in its inverted and folded condition.

'lhe braces m are bolted, to secure the rails a a' iu their proper xed relations.

Having fully described my improved-barrow,

What I claim, and desire to secure by Letters Patent, is

The arrangement of the sections A B O, for transportation from place to place, by reversing the position of the barrow upon the ground, and folding the sections in the manneldescribed.

In testimony whereof, I have hereunto set my hand,

this 5th day of May, 1868. n

ISAAC GRUM.
